Initially contents of accumulator A = AA H.
The instruction CPI 99 H compares the data 99H w ith the content of accumulator (A). This comparison is made by subtracting 99 H from contents of A i.e. AA H.
The contents of accumulator will remain unaffected but status of result will be reflected by flags
The instruction CPI 99 H compares the data 99H w ith the content of accumulator (A). This comparison is made by subtracting 99 H from contents of A i.e. AA H.
The contents of accumulator will remain unaffected but status of result will be reflected by flags
Hence, after comparison both carry and zero flags will be reset
